Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing artificial teeth often result in color mismatches due to subjective user determination, are complex, and costly, leading to inconsistent quality.
Innovation Solution
A method and system that involves photographing a target tooth, correcting images using a correction constant, extracting specific tooth areas, removing noise caused by reflected light, and generating artificial tooth manufacturing information using pixel values, which can be easily generated using a smartphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If subjective user determination is used for manufacturing artificial teeth, then user experience and career judgment are utilized, but color and shape mismatches occur due to subjectivity
Solution Approach 1:
The patent replaces the mechanical/subjective visual determination system with an automated image processing system. A photographing unit captures tooth images, and an image processing unit automatically analyzes color values and generates manufacturing information, eliminating subjective user determination while improving color measurement accuracy and matching reliability
Solution Approach 2:
The system enables self-service by allowing the photographing unit and image processing unit to automatically capture, analyze, and generate manufacturing information without requiring expert user judgment. The automated processing of pixel values and color data removes dependency on user experience and career knowledge
2Measurement precision
If complex existing systems are used for tooth color measurement, then measurement capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent uses a simple photographing unit to create a digital copy of the tooth instead of requiring complex optical measurement systems. The image processing unit then analyzes this digital copy to extract color information, achieving accurate tooth color measurement while keeping device complexity low through software-based processing rather than hardware complexity
Solution Approach 2:
The system replaces expensive, complex measurement equipment with a simple photographing unit and automated image processing software. This approach uses inexpensive digital imaging technology instead of costly optical measurement systems, reducing both device complexity and cost while maintaining measurement capability

AI summary
An artificial tooth manufacturing information generation method is provided. The artificial tooth manufacturing information generation method may include the steps of: photographing a target tooth to acquire a primary image; correcting the primary image to acquire a secondary image; selecting an area including the target tooth from the secondary image to extract a tertiary image; selecting a noise area caused by reflected light from the tertiary image and then correcting the noise area, to acquire a quaternary image; and generating artificial tooth manufacturing information by using a pixel value of the target tooth included in the quaternary image.
